How can I customize what's in the email to my clients when I send an invoice?What's populating automatically doesn't make sense. This seems to be new.

Thank you for bringing our attention to this matter, @nanetteholt.

Invoices represent the communication between you and the customer. That's why I understand the importance of using the correct salutation and punctuation in a business. 

Upon checking my resources here, the report (INV-87997) about the message from the invoice email you mentioned has been closed. Since you're still experiencing the same issue, I recommend contacting our Support Team. They can figure out what happened to your sales form and provide resolutions.

Here's how:

1. Go to the Help icon and choose Search.
2. Click the Contact Us button and enter your concern.
3. Press Continue.
